Filed: 1987-02-18
Abstract: The invention relates to the novel pWS101 plasmid, which is obtained from a gene of Saccharomyces cerevisiae yeast, as well as its use for the production of the enzyme L-aspartate : 2-oxoglutarate aminotransferase E.C.2.6.1.1. An object of the invention is to provide a means for high expression of the enzyme L-aspartate : 2- oxoglutarate aminotransferase, E.C.2.6.1.1., so that production is achieved with minimal expenditures of time and money, as well as easily and with a high degree of purity. This is achieved by the pWS101 plasmid, characterised by the features:   1) it is capable of being multiplied in microorganisms of the species Saccharomyces cerevisiae and of the species Escherichia coli; 2) it carries the ASP5 gene of Saccharomyces cerevisiae, which encodes the enzyme L-aspartate : 2- oxoglutarate aminotransferase, E.C.2.6.1.1., on 3) a "shuttle" vector containing a centromere region (CEN4) of Saccharomyces cerevisiae (YCp50).   A novel pWS101 plasmid comprising a vector containing the CEN4 centromere region of Saccharomyces cerevisiae, and the ASP5 gene of Saccharomyces cerevisiae encoding the enzyme L- aspartate : 2-oxoglutarate aminotransferase (E.C.2.6.1.1), the plasmid being capable of multiplying in a microorganism selected from the group consisting of Saccharomyces cerevisiae and Escherichia coli. A process for cloning the plasmid and a simple method of producing highly pure 1-aspartate : 2-oxoglutarate aminotransferase (E.C.2.6.1.1) comprising high expression of the enzyme gene with low expenditure of time and money.

Title: Anchored nut assembly
Inventor: OLLIS MARTIN GEORGE
IPC: F16B37/04
Filed: 1990-03-07
Abstract: A nut fastener device for a blind hole anchor has the nut 14 made frusto-conical with the smallest diameter knurled at 30 and with the largest diameter provided with relieved and back tapered flanks 20. The nut is made integral with a sleeve 10 having flange 12 and a further knurled zone 32, and a sheer zone 16 between the sleeve and nut. During the installation the nut is pulled into the sleeve to expand the sleeve and deform it to the cross sectional shape of the nut so as to provide an angular fix. The sleeve is effectively fixed to the sheet material by the flange on the one side and the deformation of the sleeve on the other side of the sheet. The knurled bands which become axially aligned increase the angular hold of the device in the sheet and of the nut in the sleeve. <IMAGE>

Title: Hydraulic master cylinder
Inventor: FARR GLYN PHILIP REGINALD
IPC: B60T11/224
Filed: 1990-07-17
Abstract: A master cylinder/serve combination includes a primary piston formed by an inner portion (33) slidingly and sealingly mounted in an annular outer portion (34), reaction forces being fed back by the inner portion (33) through an elastomeric reaction disc (37) to the input member (40) and the outer piston (34) being connected to the serve piston by a tubular rod (6). An expander chamber (10) houses piston (11) which is driven to the right when pressure in the primary chamber (7) reaches a predetermined value to cause fluid to flow into a secondary chamber (9) located behind the primary piston seal (30) to reduce the effective area of the primary piston to that (A2) of the tubular rod (6). Because feedback forces are always generated only by the inner piston (33) there is no discontinuity in pedal feel when the expander piston (11) commences movement. <IMAGE>

Title: Latch for tilting rotatable tower
Inventor: MILLER DAVID B
IPC: E05C1/10
Filed: 1991-09-03
Abstract: An apparatus has a support (14) with a tower (12) pivotally attached and movable relative to it between a raised and a lowered position. The tower is rotatable to and from a predetermined position about a longitudinal axis thereof when the tower is in the raised position. A latch device (22) is displaceable between a secured position and a non-secured position, the lower being prevented from moving to the lowered position when the tower is raised and the latch device is in the secured position. A release system prevents displacement of the latch device from the secured position when the tower is not in the predetermined and raised positions but permits displacement of the latch device from the secured position when the tower is in the predetermined and raised positions. The latch device includes a plunger (24) and a biasing member (26) located within a latch housing. The release system includes a contact element (31) which is connected to the plunger and which allows the plunger 24 to retract only when the element (31) can enter a hole (46) in a plate (28) which is fast with the tower. <IMAGE>

Title: Surface treatment of metals at low pressure
Inventor: MATTHEWS ALLAN
IPC: C23C8/38
Filed: 1991-11-08
Abstract: A method of surface hardening metals (in particular stainless steel) comprises heating the component in a chamber to a temperature of less than 550 DEG C, at a pressure of less than 10mTorr (eg 7.5m Torr) containing an element which reacts with the surface of the metal and being in ionized form by use of a plasma in the presence of a gas or gas mixture. This mixture may contain carbon (eg acetylene) or nitrogen containing gases eg nitrogen or a gas containing both carbon and nitrogen. The gas is ionized by a low pressure d.c. negative workpiece bias or r.f. plasma system so that carbon, nitrogen (or both) enter the surface of the metal. An electron emission source, which may be a negatively biased, heated tungsten filament, may provide plasma enhancement independently of workpiece voltage and chamber pressure parameters. In addition, an earthed hot tungsten filament may provide additional substrate heating conventional nitriding may be carried out as a pre-treatment and the method is particularly suitable for treating steels. An apparatus for carrying out the method is also disclosed (see Fig). Hard diffusion layers with superior combinations of wear, fatigue and/or corrosion resistance are produced depending on gas mixture, at a low temperature (as low as 270 DEG C). The range of materials which can be treated by this technique, without the need for post-finishing (either by heat treatment or machining operations), is superior to that achievable by any other single plasma diffusion process. <IMAGE>
